摘要
介绍高强度与高性能混凝土和普通混凝土性能特征的区别。对配制混凝土原材料的质量要求,水泥、外加剂与掺合料等组成的相容性及相互作用的问题进行论述。介绍加掺合料,最大限度地减少水泥用量降低水化热、改善混凝土的施工性能、减少收缩与裂缝、提高混凝土的耐久性等问题的研究成果。提出高强度与高性能混凝土的质量控制、质量评定及解决质量问题的一些技术措施。
The paper indicates the difference of performance characteristics between high-strength & high performance concrete and ordinary concrete. As to the quality requirement for raw material of mixed concrete , the consistence and interaction problems in respect of cement, additive and admixture are remarked. The admixture adding into the concrete can reduce an amount of cement and hydration heat to the greatest extent, improve the workability of concrete and increase the durability of concrete, etc. The quality control and quality evaluation of high-strength and high-performance concrete as well as how to solve technical quality problems are brought up.
